    descriptionProblems addressed by these patches : I Arbitrary code execution and denial of service vulnerabilities This release fixes a security vulnerability that could allow a guest operating system user with administrative privileges to cause memory corruption in a host process, and thus potentially execute arbitrary code on the host. (CVE-2007-4496) This release fixes a denial of service vulnerability that could allow a guest operating system to cause a host process to become unresponsive or exit unexpectedly. (CVE-2007-4497) Thanks to Rafal Wojtczvk of McAfee for identifying and reporting these issues. II Hosted products DHCP security vulnerabilities addressed This release fixes several vulnerabilities in the DHCP server that could enable a specially crafted packets to gain system-level privileges. (CVE-2007-0061, CVE-2007-0062, CVE-2007-0063) Thanks to Neel Mehta and Ryan Smith of the IBM Internet Security Systems X-Force for discovering and researching these vulnerabilities. III Windows based hosted product vulnerability in IntraProcessLogging.dll and vielib.dll. This release fixes a security vulnerability that could allow a malicious remote user to exploit the library file IntraProcessLogging.dll to overwrite files in a system. (CVE-2007-4059) This release fixes a security vulnerability that could allow a malicious remote user to exploit the library file vielib.dll to overwrite files in a system. (CVE-2007-4155) Thanks to the Goodfellas Security Research Team for discovering and researching these vulnerabilities. IV Escalation of privileges on Windows hosted systems This release fixes a security vulnerability in which Workstation was starting registered Windows services in an insecure manner. This vulnerability could allow a malicious user to escalate user privileges. Thanks to Foundstone for discovering this vulnerability. V Potential denial of service using VMware Player This release fixes a problem that prevented VMware Player from launching. This problem was accompanied by the error message VMware Player unrecoverable error: (player) Exception 0xc0000005 (access violation) has occurred. VI ESX Service Console updates a. Service console package Samba, has been updated to address the following issues : Various bugs were found in NDR parsing, used to decode MS-RPC requests in Samba. A remote attacker could have sent carefully crafted requests causing a heap overflow, which may have led to the ability to execute arbitrary code on the server. (CVE-2007-2446) Unescaped user input parameters were being passed as arguments to /bin/sh. A remote, authenticated, user could have triggered this flaw and executed arbitrary code on the server. Additionally, this flaw could be triggered by a remote unauthenticated user if Samba was configured to use the non-default username map script option. (CVE-2007-2447) Thanks to the Samba developers, TippingPoint, and iDefense for identifying and reporting these issues. Note: These issues only affect the service console network, and are not remote vulnerabilities for ESX Server hosts that have been set up with the security best practices provided by VMware. http://www.vmware.com/resources/techresources/726 b. Updated bind package for the service console fixes a flaw with the way ISC BIND processed certain DNS query responses. ISC BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols. Under some circumstances, a malicious remote user could launch a Denial-of-Service attack on ESX Server hosts that had enabled DNSSEC validation. (CVE-2007-0494) Note: These issues only affect the service console network, and are not remote vulnerabilities for ESX Server hosts that have been set up with the security best practices provided by VMware. http://www.vmware.com/resources/techresources/726 c. This patch provides updated service console package krb5 update. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the names CVE-2007-2442, CVE-2007-2443, and CVE-2007-2798 to these security issues. Thanks to Wei Wang of McAfee Avert Labs discovered these vulnerabilities. Note: The VMware service console does not provide the kadmind binary, and is not affected by these issues, but a update has been provided for completeness. d. Service console update for vixie-cron This patch provides an updated service console package vixie-cron. Cron is a standard UNIX daemon that runs specified programs at scheduled times. A denial of service issue was found in the way vixie-cron verified crontab file integrity. A local user with the ability to create a hardlink to /etc/crontab could potentially prevent vixie-cron from executing certain system cron jobs. (CVE-2007-1856) Thanks to Raphael Marichez for identifying this issue. e. Service console update for shadow-utils This patch provides an updated shadow-utils package. A new user

         provided for completeness.
    
    d.   Service console update for vixie-cron
    
         This patch provides an updated service console package vixie-cron.
         Cron is a standard UNIX daemon that runs specified programs at
         scheduled times.
    
         A denial of service issue was found in the way vixie-cron verified
         crontab file integrity. A local user with the ability to create a
         hardlink to /etc/crontab could potentially prevent vixie-cron from
         executing certain system cron jobs. (CVE-2007-1856)
    
         Thanks to Raphael Marichez for identifying this issue.
    
    e.   Service console update for shadow-utils
    
         This patch provides an updated shadow-utils package.  A new
         user's mailbox, when created, could have random permissions for a
         short period. This could enable a local malicious user to
         read or modify the mailbox. (CVE-2006-1174)
    
    f.  Service console update for OpenLDAP
    
         This patch provides a updated OpenLDAP package. A flaw could
         allow users with selfwrite access to modify the distinguished
         name of any user, instead of being limited to modify only
         their own distinguished name. (CVE-2006-4600)
    
    g.   Service console update for PAM
    
         This patch provides an updated PAM package A vulnerability was
         found that could allow console users with access to certain device
         files to cause damage to recordable CD drives. Certain file
         permissions have now been modified to disallow access.
         (CVE-2004-0813)
    
         A flaw was found with console device permissions. It was possible
         for various console devices to retain ownership of the previoius
         console user after logging out, which could result in leakage of
         information to an unauthorized user. (CVE-2007-1716)
    
    h.   Service console update for GCC
    
         This patch provides security fixes for the service console GNU
         Compiler Collection (GCC) packages that include C, C++, Java,
         Fortran 77, Objective C, and Ada 95 GNU compilers and related
         support libraries.
    
         A flaw was found in the fastjar utility that could potentially
         allow a malicious user to create a JAR file which, if unpacked
         using fastjar, could write to any file that an authorized user had
         write access to. (CVE-2006-3619)
    
         Thanks to Jürgen Weigert for identifying this issue.
    
    i.   Service Console update for GDB
    
         This patch provides a security fix for the service console GNU
         debugger (GDB).  Various vulnerabilities were found in GDB. These
         vulnerabilities may allow a malicious user to deceive a user into
         loading debugging information into GDB, enabling the execution of
         arbitrary code with the privileges of the user. (CVE-2006-4146)"

    descriptionFrom Red Hat Security Advisory 2007:0345 : Updated vixie-cron packages that fix a denial of service issue are now available. This update has been rated as having moderate security impact by the Red Hat Security Response Team. The vixie-cron package contains the Vixie version of cron. Cron is a standard UNIX daemon that runs specified programs at scheduled times. Raphael Marichez discovered a denial of service bug in the way vixie-cron verifies crontab file integrity. A local user with the ability to create a hardlink to /etc/crontab can prevent vixie-cron from executing certain system cron jobs. (CVE-2007-1856) All users of vixie-cron should upgrade to these updated packages, which contain a backported patch to correct this issue.
